The 1989 Oldsmobile Cutlass Supreme sits firmly in the late front-wheel-drive personal coupe era, when styling, trim level, and suspension package could change the character of the car as much as the name on the decklid. For owners today, that makes tire selection less about broad Oldsmobile fitment and more about matching the exact Cutlass Supreme configuration. This model uses radial tires, with primary sizes ranging from 195/75R14 and 205/70R15 to 215/65R15 and 215/60R16 depending on sub-model. Available choices span traditional whitewall looks, blackwall performance-oriented styles, redline, and raised-letter treatments. The right decision starts with the exact sub-model and wheel diameter, then balances appearance, road use, and restoration goals.
Which Tire Size Is Right for The 1989 Oldsmobile Cutlass Supreme
Four primary tire sizes apply to the 1989 Oldsmobile Cutlass Supreme, and the correct one depends on the exact sub-model and wheel diameter. This is a radial-only fitment, but the car uses 14-inch, 15-inch, and 16-inch rims across the range, so confirming the actual wheel on the car is the first step before comparing sidewall style, tire series, or overall presentation.
195/75R14 is a metric radial size: 195 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 14 is the rim diameter in inches. On the 1989 Oldsmobile Cutlass Supreme, this size suits configurations that use a 14-inch wheel and a more traditional full-profile radial look. Available choices include Coker Classic, Tornel, Maxxis, and Travelstar options, with both wide whitewall and narrow whitewall presentations. This size is worth considering when the car retains its original 14-inch wheel setup and appearance matters as much as road manners.
205/70R15 is a metric radial size with a 205-millimeter nominal section width, a 70-series profile, radial construction, and a 15-inch rim diameter. For the 1989 Oldsmobile Cutlass Supreme, it represents one of the main 15-inch fitments and opens up the broadest mix of product styles. Choices include blackwall, narrow whitewall, wide whitewall, and a bias-look radial, with brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. It is the size to evaluate when the car carries 15-inch wheels and the goal is to balance traditional styling with a wider range of product character.
215/60R16 is a metric radial size in which 215 is the nominal section width in millimeters, 60 is the aspect ratio, R means radial, and 16 denotes the rim diameter in inches. On the 1989 Oldsmobile Cutlass Supreme, this size is tied to the 16-inch-wheel configuration rather than the more common 14- and 15-inch setups. Its shorter-profile format gives it a distinctly different fitment role within the model range. Choosing this size starts with confirming that the car is the sub-model that uses 16-inch wheels, since a 16-inch tire cannot be treated as interchangeable with the 14- or 15-inch fitments.

215/65R15 is a metric radial size with a 215-millimeter nominal section width, a 65-series profile, radial construction, and a 15-inch rim. Within the 1989 Oldsmobile Cutlass Supreme lineup, this size is associated with FE3 Suspension Package applications and offers a noticeably different mix of appearance choices than the other 15-inch size. Available options include Goodyear, Cooper, and BFGoodrich products in OWL, raised white letter, redline, and wide whitewall styles. This size makes the most sense once the FE3-equipped configuration and actual 15-inch wheel are confirmed, especially if sidewall presentation is part of the decision.
Sub-model fitment matters on the 1989 Oldsmobile Cutlass Supreme because tire size changes across the lineup. Some versions share the same size choices, while others move to a different 15-inch or 16-inch setup, so identifying the exact trim and wheel diameter should come before selecting a tire style.

1989 Oldsmobile Cutlass Supreme Base
The 1989 Oldsmobile Cutlass Supreme Base uses either a 195/75R14 radial or a 205/70R15 radial, depending on the wheel setup on the car. That makes wheel diameter the key checkpoint before comparing whitewall, blackwall, or other product variations within the correct size.
The 1989 Oldsmobile Cutlass Supreme International uses the 215/60R16 radial size. Tire selection here begins with confirming the 16-inch wheel, since this fitment stands apart from the 14-inch and 15-inch sizes used elsewhere in the Cutlass Supreme range.
The 1989 Oldsmobile Cutlass Supreme SL shares the same two-size pattern as the Base model, using either 195/75R14 or 205/70R15 radial tires. The practical choice comes down to verifying whether the car has 14-inch or 15-inch wheels, then choosing the sidewall style and tire series that best suit the car.
The 1989 Oldsmobile Cutlass Supreme SL w/FE3 Suspension Pkg. uses the 215/65R15 radial size. That creates a more focused tire decision centered on 15-inch fitment, with choices that range from whitewall and redline styling to raised white letter performance-oriented looks.
The 1989 Oldsmobile Cutlass Supreme w/FE3 Suspension Pkg. also uses the 215/65R15 radial size. For this configuration, selection is less about finding the right diameter and more about choosing the right sidewall treatment, rim-width compatibility, and overall appearance for the car’s intended use.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners usually need to sort out exact tire size, wheel diameter, and sub-model before choosing tires for a 1989 Oldsmobile Cutlass Supreme. The questions below focus on fitment, sidewall and brand choices, restoration-minded appearance, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 1989 Oldsmobile Cutlass Supreme?
The 1989 Oldsmobile Cutlass Supreme uses four primary radial tire sizes across the model range: 195/75R14, 205/70R15, 215/60R16, and 215/65R15. The Base and SL models use either 195/75R14 or 205/70R15, the International uses 215/60R16, and FE3 Suspension Package versions use 215/65R15.
That means the correct answer depends on the exact sub-model and the wheel diameter currently on the car. A Cutlass Supreme that has been changed to a different factory-style wheel or an aftermarket setup should be checked carefully, since a 14-inch, 15-inch, or 16-inch tire choice starts with matching the wheel itself.
What size rim does a 1989 Oldsmobile Cutlass Supreme use?
A 1989 Oldsmobile Cutlass Supreme can use 14-inch, 15-inch, or 16-inch rims, depending on the sub-model and tire size. The 195/75R14 fitment uses a 14-inch rim, both 205/70R15 and 215/65R15 use 15-inch rims, and 215/60R16 uses a 16-inch rim.
Wheel diameter is the first thing to confirm before buying tires for this car, especially because two different 15-inch tire sizes appear in the lineup. Looking at the current tire sidewall and measuring the wheel if needed is smarter than assuming every Cutlass Supreme from 1989 used the same rim or the same profile.
Do all 1989 Oldsmobile Cutlass Supreme sub-models use the same tire size?
No. The 1989 Oldsmobile Cutlass Supreme lineup uses different tire sizes by sub-model. Base and SL versions use either 195/75R14 or 205/70R15, the International uses 215/60R16, and FE3 Suspension Package versions use 215/65R15.
This matters because tire selection is not just a question of brand or sidewall style on this car. Identifying the exact sub-model narrows the correct diameter and profile first, and that keeps a buyer from comparing 16-inch International tires against 14-inch or 15-inch options meant for a different Cutlass Supreme configuration.
Choosing the Right Tire
What should I consider when choosing a 1989 Oldsmobile Cutlass Supreme tire?
Start with the correct tire size and wheel diameter for the exact 1989 Oldsmobile Cutlass Supreme sub-model. After that, the main factors are radial construction, rim-width compatibility where stated, load figures where relevant, and the kind of sidewall presentation that suits the car, whether that is whitewall, blackwall, redline, OWL, or raised white letter.
A Base or SL model with 14-inch wheels leads to a different set of options than an FE3 or International model. It helps to match the tire not only to the rim but also to the car’s purpose, whether that is a restoration-minded appearance, casual cruising, or a more performance-flavored look within the proper size.
What sidewall styles are available for 1989 Oldsmobile Cutlass Supreme tires?
Sidewall choices for the 1989 Oldsmobile Cutlass Supreme vary by tire size and include wide whitewall, narrow whitewall, blackwall, redline, OWL, and RWL. The broadest whitewall selection appears in 195/75R14 and 205/70R15, while 215/65R15 adds more sporty presentation options such as redline and raised white letter styles.
That variety lets the tire change the personality of the car even when the wheel diameter stays the same. A conservative coupe may look more at home on whitewalls, while an FE3-equipped car may lean toward RWL or OWL styling, so appearance should be considered alongside fitment rather than treated as an afterthought.
What brands offer tires for the 1989 Oldsmobile Cutlass Supreme?
Available brands for 1989 Oldsmobile Cutlass Supreme tire sizes include Coker Classic, Tornel, Maxxis, Travelstar, Michelin, Avon, American Classic, Dunlop, Goodyear, Cooper, and BFGoodrich. Brand availability changes by size, so the names available in 195/75R14 are not exactly the same as the choices offered in 205/70R15 or 215/65R15.
Brand choice should come after the correct size is confirmed, not before. Once the fitment is settled, comparing the available series, sidewall styles, rim-width specs, and load figures can help narrow the field, especially on this car where some sizes lean toward traditional whitewall looks and others toward more performance-oriented styling.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Oldsmobile Cutlass Supreme?
A period-style 1989 Oldsmobile Cutlass Supreme tire starts with the correct size for the exact sub-model, then moves to the overall look of the tire. Whitewall radials in 195/75R14 and 205/70R15 can suit a traditional late-1980s personal coupe presentation, while 215/65R15 also offers redline and raised white letter options for a more assertive FE3-era appearance.
The right visual choice depends on how the car is being presented rather than on a single universal style. Owners pursuing exact originality should compare the current tire plan with marque references, period photos, or vehicle-specific documentation, because the proper size can still be paired with several different sidewall treatments.
How does tire construction affect the appearance of a restored 1989 Oldsmobile Cutlass Supreme?
On the 1989 Oldsmobile Cutlass Supreme, primary fitment is radial across the lineup, so the appearance difference comes more from profile and sidewall style than from choosing between bias-ply and radial construction. A 75-series or 70-series radial can look more traditionally full-bodied, while a 60-series fitment gives the car a lower-profile visual stance.
That makes wheel diameter and sidewall presentation especially important on a restored example. A whitewall radial can support a softer luxury-oriented look, while blackwall, redline, OWL, or RWL options can shift the same car toward a sportier visual character without changing the underlying requirement for the correct sub-model fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Oldsmobile Cutlass Supreme?
Yes. Modifications can affect tire fitment on a 1989 Oldsmobile Cutlass Supreme even when the tire size appears close to stock. Aftermarket wheels, changes in wheel width or offset, suspension alterations, lowering, and body or brake changes can all influence how a 14-inch, 15-inch, or 16-inch tire actually sits on the car.
That is especially important here because this model already uses several factory size and rim combinations. A modified car should be checked for steering clearance, inner fender space, and overall wheel compatibility before choosing a replacement tire, rather than assuming that any size associated with a Cutlass Supreme will suit the current setup.
What should I inspect before driving a 1989 Oldsmobile Cutlass Supreme on new tires?
Before driving a 1989 Oldsmobile Cutlass Supreme on new tires, inspect the wheels for correct diameter and sound condition, confirm proper inflation, and look over the suspension and steering for obvious wear that could affect how the new tires behave. It also helps to verify that the selected size matches the exact sub-model and wheel on the car.
A short, careful road test is useful after installation to confirm there is no rubbing, vibration, or pull. Cars that spend long periods parked deserve extra attention, since wheel corrosion, dried valve stems, alignment drift, and neglected front-end components can show up quickly once fresh tires are put back into service.
How should tires on a collector 1989 Oldsmobile Cutlass Supreme be maintained?
Tires on a collector 1989 Oldsmobile Cutlass Supreme should be checked regularly for pressure, tread wear, cracking, bulges, cuts, and signs of air loss. Even a lightly driven car can age its tires through time, storage conditions, and long stationary periods, so visual condition matters just as much as mileage.
Storage habits make a real difference on late-classic cars that are used seasonally. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the sidewalls, and moving the car periodically can reduce flat spotting. Any tire that shows age-related deterioration deserves attention before regular road use resumes.
